Kegel exercise is commonly prescribed to improve the urination and evacuation capabilities of a patient. Assistive devices developed for Kegel exercise are found limited in terms of clinical effectiveness and motivation. The present study is intended to develop a serious game to support active and sustainable Kegel exercise for patients. A four-step process (benchmarking, analysis of patent and technology, ideation of hardware and software, and implementation) is applied in the present study to development of a Kegel serious game. The proposed serious game for active Kegel exercise needs to be validated in urology clinics.
